% 使用嵌套函数减少变量传递 bigData = rand(1e4); processSub(bigData); function processSub(data) % 处理逻辑 end end 2.4. 避免内存拷贝 削减中间变量,使用in-place操作直接覆盖变量。 如a=2; b=a+3; c=b+a;每次进行赋值时,中间变量会增加本来不必要的内存占用,同时增加多余计算步骤带来的时间消耗。
fori =1:blockSize:size(bigData,1) block =bigData(i:i+blockSize-1, :); processBlock(block); % 自定义处理函数 end 三、硬件配置建议 四、扩展解决方案 云平台部署:通过AWS/GCP临时租用高配实例(如r5.xlarge:16vCPU+128GB RAM)应对短期计算需求 代码级优化:使用parfor替代for循环,GPU加速函数(如gpuA...
You can create an ImageDatastore object using the imageDatastore function, specify its properties, and then import and process the data using object functions. CreationSyntax imds = imageDatastore(location) imds = imageDatastore(location,Name,Value)...
